We evaluate graft pathology in healthy pediatric transplant recipients with low\u2010maintenance immunosuppressive medications to assess whether protocol biopsies are helpful for adapting immunosuppression and protecting long\u2010term graft function. Liver biopsies were performed on 60 healthy pediatric liver transplant recipients, and histological findings were correlated with laboratory, serological, and radiological results. Fourteen patients (23%) were diagnosed with acute or early chronic rejection, and immunosuppressive medications were increased in these children. Liver function tests did not correlate with histological findings. The incidence of fibrosis was 36% in transplant recipients five or more years after liver transplantation. We observed an unexpectedly high prevalence of rejection and fibrosis in children with no laboratory abnormalities, which led to changes in their immunosuppressive medications. Scheduled biopsies appear to be useful in pediatric transplant recipients with low immunosuppressive medications for early detection of morphological changes in liver transplants. Further studies are needed to evaluate whether adaption of immunosuppression helps to reduce tissue damage and the incidence of allograft dysfunction in the long term.<\/jats:p>","DOI":"10.1111\/petr.12119","type":"journal-article","created":{"date-parts":[[2013,7,9]],"date-time":"2013-07-09T12:11:49Z","timestamp":1373371909000},"page":"543-549","source":"Crossref","is-referenced-by-count":34,"title":["Liver
